Where are the include and link directories for packages installed through Homebrew

·1 min

I was trying to build a project which had dependencies of gflags and glog and used cmake as the build tools.

I was using Homebrew on MacOSX, so I went ahead and installed the dependencies like so:

shell brew install glog brew install gflag Now, I wanted to add include path and link path for these libs in the project. My first shot was to add a CXXFLAGS variable and expected that cmake would pick it up.

export CXXFLAGS="-I/usr/local/Cellar/glog/0.3.4/include -I/usr/local/Cellar/gflags/2.1.2/include/"

cmake did not pick up this because it never used CFLAGS or CXXFLAGS.

Next, I added the dependency manually in the CMakeLists.txt file using the include_directories and link_directories like so:


This approach was not scalable. I searched for a bit and found an acceptable solution. I added /usr/local/include and /usr/local/lib in the include and the link path respectively.


This works! I am of the opinion that we can do better, but as of now I am okay with this.
