I got the following errors when CMake tests my compilers. The problem is that it seems CMake is checking /usr/bin/gcc, instead of the /usr/bin/armv7a-cros-linux-gnueabi-gcc it should have checked.I manually tried /usr/bin/armv7a-cros-linux-gnueabi-gcc, and it compiles fine, and manually tried /usr/bin/gcc, it failed with the same errors as below. So why CMake identified the correct compiler (armv7a-cros-linux-gnueabi-gcc), but when it checked the compiler (gcc), it used the wrong one?

Try removing the whole build tree, it may have some left over stuff from a wrong selection of the compiler at some point.
