Building on macOS is very similar; would be nice if it was included in the readme.

Prereqs:

• xcode-select --install (this installs the xcode command line tools including compilers, libraries, etc).
• brew install glew cmake (needed libraries not already in macOS)

Building and installing:

• cd build
• cmake ..
• make
• sudo make install
• sudo update_dyld_shared_cache

For MacOS, glew installed by brew the INCLUDE_DIRS should be "/opt/homebrew/include", this is a small tip

if(UNIX)
set ( INCLUDE_DIRS
"/usr/include"
"/usr/local/include"
"/usr/include"
"/opt/homebrew/include"
${INCLUDE_DIRS}
)
endif(UNIX)

sudo make install

does not update the dynamic linker after installing. The makefile should include
sudo ldconfig
after the static object files have been copied

If a user has manually built and installed GLEW from source, the default include path for the headers is
<glew.h>
but if the user has installed canonical's version of GLEW via aptitude, the default include path for the headers is
<GL/glew.h>
this does not cause GLTools to fail to build, but it does cause anything that #includes GLTools to fail to build.
