I have the same issue building KiCad.  CMake does not appear to know how
to properly define the default search path for MinGW.  It probably sees
MSYS defined and sets the default search path to /usr which is not what
you want unless you are actually building an msys application.  You can
find out what this path actually is by printing the CMAKE_PREFIX_PATH
variable.  You can override this by calling cmake with
-DCMAKE_PREFIX_PATH=/mingw64.  You shouldn't have to rename
/usr/bin/pkg-config.exe.
