cmake.bbclass: allow cmake to find hosttools
PATCH v2 1/1 cmake.bbclass: allow cmake to find hosttools
Currently the generated toolchain file is unable to find hosttools as they do not appear in the search paths.
One example where this is useful is for projects that query git for their version number as git is usually provided via HOSTTOOLS.
Just adding HOSTTOOLS_DIR is not enough as binaries are located directly under ${HOSTTOOLS_DIR}. Like ${HOSTTOOLS_DIR}/git for example.
CMake however only searches in [s]bin sub directories of the paths specified in CMAKE_FIND_ROOT_PATH. Explicitly adding / to CMAKE_SYSTEM_PROGRAM_PATH makes CMake look in the right location.
