Thanks for taking the time to reply. I hadn't used `cmake --trace`
before. When running it, I can see that the process gets stuck in
"/usr/share/cmake-3.3.1/Modules/CMakeDetermineSystem.cmake(48):
exec_program(uname ARGS -s OUTPUT_VARIABLE CMAKE_HOST_SYSTEM_NAME )"


I've manipulated that cmake file to use a static system name, and the
problem now arises in "Modules/CMakeDetermineCompilerId.cmake" at

execute_process(COMMAND ${CMAKE_${lang}_COMPILER}
${CMAKE_${lang}_COMPILER_ID_ARG1}
${CMAKE_${lang}_COMPILER_ID_FLAGS_LIST} ${testflags} ${src}
WORKING_DIRECTORY ${CMAKE_${lang}_COMPILER_ID_DIR} OUTPUT_VARIABLE
CMAKE_${lang}_COMPILER_ID_OUTPUT ERROR_VARIABLE
CMAKE_${lang}_COMPILER_ID_OUTPUT RESULT_VARIABLE
CMAKE_${lang}_COMPILER_ID_RESULT )

It looks as though there is a problem with `execute_process` (and the
deprecated `exec_program`). I haven't tried uninstalling the Win32
version of CMake, but it's definitely the CygWin version that is
running.

Best wishes,

Nick
