Re: [Help-gsl] CMake build support for GSL

The error might be on my side, but this is not what I experience. I create 
VS2013 Project, and even though the CMAKE_INSTALL_PREFIX is set to 
C:\Kellekek\GSL I have the libs installed under C:\Kellekek\GSL\lib for all 
configurations. Since GSL is not a library that canonically has different names 
for the different configurations, I always have to create the Release and Debug 
directories by hand in the install location and copy the libs over.

I fetched the CMake file just 2 days ago, it’s not outdated.

What is the way of specifying whether I want a dynamic library or a static one? 
It seems that the CMake file assumes I want a static lib, but infact I prefer 
dll-s. The option does not come up when configuring with cmake-gui.exe

Any insights as to what I’m doing wrong?

Hi Máté,

I'm glad you liked it.

As for multi-configuration builds, they are already supported. When using a 
multi-configuration generator such as MSVC, release binaries are placed in the 
Release directory and debug ones are placed in the Debug directory. You can 
also have separate out-of-tree builds with different settings for 
single-configuration CMake generators such as Makefile generator.

Best regards,

I have recently posted how nice it would be if NuGet or Chocolatey would get 
some GNU loving, and GSL could be the first one. The CMake file you created 
does show a lot of and great congrats. I managed to build the libraries just 
fine, I would have just one comment:

It would be nice if the CMakeLists.txt file supported multi-configuration 
builds without seperate install prefixes. For eg. if on Windows, where building 
under lib/Debug and lib/Release is very common, it would be nice if I wouldn’t 
have to always build and create the directory structure myself, but have the 
makefile do it for me.

Other than this, fantastic work!

Hi Victor,

   Thanks it looks like you did a lot of work on this. I was able to
build the current git repository easily with your script. I've added the
file in contrib/CMakeLists.txt so others can use it if they want.
