custom.pro is included in librecad.pro by this line:

exists( custom.pro ):include( custom.pro )

I suspect that the author expected that the things defined in custom.pro will be visible to the projects in sub-directories. However, this is not the case (I don't know if this is a bug in qmake or it is so by design). To make it useful above line should be copied to all .pro files.

I use this file kind of to indicate library and include paths on Windows and is quite useful to me.

I'm posting here instead of a pull request because the purpose of this file may be other than the one that I assume. Is it ok to add the line:

# custom definitions from the user
exists( custom.pro ):include( custom.pro )

in common.pro? This will include custom.pro in all projects that produce output:
- jwwlib
- libdxfrw
- src
- all plugins
- ttf2ltf
