I was hoping that specifying CMAKE_SYSROOT=/home/dev/arm_build in my CMAKE_TOOLCHAIN_FILE would prefix it to the search path of the find_* commands, so I won't have to modify existing Find*.cmake files. However, when I do that, cmake is unable to locate the compiler's libc files (my compiler also resides in /home/dev/arm_build) and is unable to compile a test program, not finding crt1.o, crti.o etc. Without specifying CMAKE_SYSROOT things work, it's just that I have to edit the Find*.cmake files. I can live with that, but any suggestions?
