At a quick glance, this seems to be a problem with CMake not being able to find GSL in its installed location. In other words, there is no evidence that this is a problem with GSL itself, but rather it seems to be an issue in your build setup. I'm not familiar with best practices on Windows, but if I had to debug I would start by compiling directly without the help of CMake. So you need to figure out two steps: (1) Can you compile your test program with your include path set up so that your compiler/preprocessor can correctly include the GSL header files? (2) Can you link your test executable with the library path set up so that your compiler/linker can correctly link in the GSL library and any necessary dependencies such as gslcblas and/or the standard math library? If you get these to work manually, you'll have proof positive that this is not a GSL problem. Then you'll have to figure out how to tell CMake to look for GSL in the appropriate location. That's something you may want to take up on a forum that deals specifically with building with CMake for Windows.
