Add /usr/include/Imath to includes

[Red]

I am unable to compile the latest version of Fractorium on Gentoo because /usr/include/Imath is not in the includes for the project.

I believe that has to do with OpenEXR, right? Which version are you using? Recent versions of OpenEXR changed around their includes.

Gentoo currently uses openexr-3.1.4-r1

Ok, would you be willing to make a PR with the fixes in it? I can give you PR permissions if so.

I just hand-edited every Makefile in the subdirectory to add -I/usr/include/Imath to INCPATH or whatever it was.

I don’t really know how this build system works.

[Matt Feemster]

I just added the following code to defaults.pri. Please update your code and let me know if it builds correctly on your end.

exists( /usr/include/Imath ) {
INCLUDEPATH += /usr/include/Imath
}

[Red]

Yes, that fixes it.
