Test: Honor CMAKE_CROSSCOMPILING_EMULATOR variable This CMake variable is intended to define a wrapper program for executing cross-compiled executables. However, CTest doesn't use CMAKE_CROSSCOMPILING_EMULATOR, because it isn't obvious which tests should be executed with the wrapper and which tests are scripts that don't need it. This commit manually prepends ${CMAKE_CROSSCOMPILING_EMULATOR} to all unit test command lines that execute a program built by the libjpeg-turbo build system. Thus, one can set CMAKE_CROSSCOMPILING_EMULATOR in a CMake toolchain file to (for instance) "qemu-{architecture} {qemu_arguments}") in order to execute all eligible unit tests using QEMU.
