I want to use SCIP optimization suite 6.0.2 together with the Python interface PySCIPOpt, and to enable debugging. I work in Linux - Ubuntu 18.04LTS, without sudo privileges (I avoid using sudo because I want to do the same on a cluster, where I don't have the sudo option).
I follow the installation instructions in SCIP and PySCIPOpt, and try to install SCIP in my HOME directory, specifying custom path to the cmake command.
I have done the following:
in my .bashrc I export SCIPOPTDIR=$HOME/scipoptsuite-6.0.2/build
then in ~/scipoptsuite-6.0.2:
cmake -Bbuild -H. -DCMAKE_BUILD_TYPE=Debug -DCMAKE_INSTALL_PREFIX=$SCIPOPTDIR

At this point scip and soplex binaries exist in build/bin/, and SCIP can be launched as standalone solver by executing build/bin/scip. However, the build/ directory does not contain the include/ dir required for PySCIPOpt.
So according to this, I have tried to install SCIP by running:
cd build
make install
Then the error occurs:

What have I done wrong?
A complete recipe for installing SCIP and PySCIPOpt with the debug option will be the best.
(The sudo privileges are available if needed)
Thank you.
You just need to specify a different directory for the install target. Set SCIPOPTDIR to some install/ dir instead of build/ and it should work. You cannot have install and build using the same directories.
PySCIPOpt is searching for the install directory so you always need to run install after building the project.
You don't need sudo for any of this as long as you don't want to install to some system directory.

I am building following NGraph instructions on https://github.com/NervanaSystems/ngraph
Looking at these I am assuming these variables
NGRAPH_VERSION
NGRAPH_VERSION_SHORT
NGRAPH_API_VERSION
did not get set for some reason, even though the instructions never specifically require them to be set
My installation steps are:
git clone https://github.com/csullivan/ngraph.git
cd ngraph
mkdir build
cd build
cmake .. -DCMAKE_C_COMPILER=arm-linux-gnueabihf-gcc -DCMAKE_CXX_COMPILER=arm-linux-gnueabihf-g++ -DCMAKE_INSTALL_PREFIX=/home/pi/openvino_files/ngraph/install
make -j install
I tried setting them manually in the command line and in the cmake file, adding
SET(NGRAPH_VERSION 1)
SET(NGRAPH_VERSION_SHORT 1)
SET(NGRAPH_API_VERSION 1)
but the error still did not go away. And i don't want to have to set the version manually every time.
Something else is wrong here, what am I doing wrong?
What command do I need to type in to make it build correctly?
Thanks,

Up until now I've included 3 boost libraries using

Now I've added program_options
find_package(Boost COMPONENTS system thread filesystem program_options REQUIRED)
But cmake included only system, thread and filesystem in the resulting Visual Studio 2012 project. That's why I get this error:

libssh does not use dlopen at all. It is either openssl or another library which needs dlopen and is not linked correctly.
You’re linking against the static libraries of openssl it is probably openssl which needs libdl.

-- Configuring incomplete, errors occurred!
How do I proceed?
It appears that CMake is unable to find the htmlcxx library.
In the whalebot documentation, htmlcxx is listed as a dependency.
You need to download htmlcxx, unzip it, then install it:
cd <path to unzipped htmlcxx>
./configure --enable-static=on --enable-shared=off
make
sudo make install
You may need to add #include <cstddef> to the top of html/tree.h to get it to build successfully. It will install to usr/local/ by default.
You also need icu installed if you don't already have it:
sudo apt-get install libicu-dev
Finally, you can now build and install whalebot. Again, making might fail if you have a reasonably up-to-date boost installation.
In line 57 of webspider/src/webspider_options.cpp, you need to replace boost::filesystem::initial_path().native_directory_string() with boost::filesystem::initial_path().string(). Then you should be good to build and install:
cd <path to unzipped whalebot>
mkdir build
cd build
cmake .. -DCMAKE_BUILD_TYPE=Release
make
sudo make install
This too will install to usr/local/ by default.
Check if in CMakeLists you have written find_library(..) or find_path(.), then replace it by find_package(..).
It solved the error in my case.
