[fix] Windows Compile

[bmarques1995]

The lib doesn't compile on windows without specifying glew include location, one solution is add the CMAKE_PREFIX_PATH as a build interface. For the compilation, I'm using clang

I think this may work, but seems like not idiomatic. Does GLEW contains the files for find_package(GLEW)?

@bmarques1995 I may accept, but if you could use find_package instead this for-each #52

GLEW is officially to be supported by CMake. When you compile the GLEW, you can run cmake --install ./build-dir too.

Also, any library must be installed under the compiler path. I think this solve for you but I will investigate a better way to solve this.

I think cmake --install <dir> should works for compile GLEW giving the necessary files for placing under compiler include/;bin/ path.

Find package is viable, I'll test and resend with glew installation

@bmarques1995 I know what is happening, may you are trying to compile EKG without GLEW installed (--install). I agree with you in the part of local includes. However, EKG requires all libraries installed on your compiler. On Windows, it is a really difficulty.

Vokegpu is doing a work on this to help building on Windows using the voke library/compiler/target-manager. But is not done yet, so you need to solve dependencies manually on Windows, installing under the compiler path on Windows, normally in PATH. If you use cmake --install ./build-dir this will install under the compiler path --- you can change the defined flag CMAKE_INSTALL_PREFIX to pick any place you want to installs, it includes: lib/ and include/.

Your solution works locally for solving this BUT this is not idiomatic. The only unique exception is for FreeType because the common include issue related to the Linux packages conflict, note that this issue is fixed by using an idiomatic way of CMake with find_package.

While this issue can be solved installing correct the GLEW (as discussed using --install after compiled the GLEW library). There is no reason to accept the current PR. I made builinding on Windows in the past without local includes, libraries should be installed under the compile track (not local includes but a global include per compiler as in Linux lib/, lib64, usr/include etc). I understand if this solve for local includes it is a good but this is not a real problem which make impossible to compile EKG without local include. Thanks.
