To compile ColorGrab on Linux, make sure that you have wxgtk 3.0 or newer, as well as cmake and a C++ compiler. Then run:

git clone https://github.com/Acolarh/colorgrab
cd colorgrab
cmake .
make

A Windows-installer (as well as a standalone executable) is available under releases.

To compile ColorGrab on Windows you can use MinGW. If you use MinGW you will have to manually add GDI+ headers (see this blog post) before compiling wxWidgets.

More information about compiling wxWidgets on Windows is available on the wxWidgets wiki.
