[CMake] Setting test environment on windows

Hi.

I can't belive it was so simple. In our code (I inherited it from a former employee) we had:

add_test(ut ${CMAKE_RUNTIME_OUTPUT_DIRECTORY}/ut)

I never thought there might by something wrong with it. I've changed the above to:

add_test(NAME ut COMMAND ${CMAKE_COMMAND} -E environment)

an WOW - escaping now works as expected!
Thanks David.

The following example demonstrates a way for you to achieve what you need:


  cmake_minimum_required(VERSION 2.8)
  project(t1)

  include(CTest)

  add_test(NAME test01 COMMAND ${CMAKE_COMMAND} -E environment)
  set_property(TEST test01 APPEND PROPERTY ENVIRONMENT Z1ENV=1;2;3 Z2ENV=a;b;c)

  add_test(NAME test02 COMMAND ${CMAKE_COMMAND} -E environment)
  set_property(TEST test02 APPEND PROPERTY ENVIRONMENT Z1ENV=1\;2\;3
Z2ENV=a\;b\;c)

  add_test(NAME test03 COMMAND ${CMAKE_COMMAND} -E environment)
  set_property(TEST test03 APPEND PROPERTY ENVIRONMENT "Z1ENV=1\;2\;3"
"Z2ENV=a\;b\;c")


Only test03 actually produces the sort of results you want with semi-colons embedded in the env variable value.

So:
escape the semi-colons in the PATH value and enclose "PATH=${path_value}" in double quotes

That should give you what you need.

To escape the semi-colons, use:

  string(REPLACE ";" "\\;" path_value "${path_value}")


Let us know if this works for you and what your final code looks like so others can reference it too.


HTH,
David
