[Insight-developers] CMake and external toolkits

[Bill Hoffman]

You want to use these cmake commands:
cmFindIncludeCommand
cmFindLibraryCommand

In your cmakelists file add these:

FIND_INCLUDE( FLTK_INCLUDE path1 path2 )
FIND_LIBRARY( FLTK_LIBRARY try1 try2 )

Then use FLTK_INCLUDE and FLTK_LIBRARY as a variables in the cmakelists file.
They will be put into the cache file automatically for you.
