Summary

0014306: environment variable set in a add_custom_target is forgotten

Description

Under windows, I set an environment variable and then launch a batch file which displays the value of the environment variable.

add_custom_target(test_env_var
                  COMMAND set MYENVVAR=this_is_a_test
                  COMMAND ${CMAKE_SOURCE_DIR}/echo.bat)

The variable is correctly displayed.

Under linux, I tried to do the same

add_custom_target(test_env_var
                  COMMAND export MYENVVAR=this_is_a_test
                  COMMAND ${CMAKE_SOURCE_DIR}/echo.sh)

The shell script displays an empty variable.
To be able to display the environment variable, I must do like this:

add_custom_target(test_env_var
                  COMMAND export MYENVVAR=this_is_a_test && ${CMAKE_SOURCE_DIR}/echo.sh)

And then it works.

Under linux, it's like a new shell is started each time a COMMAND is met.
Under windows, it's like a shell is started at the first COMMAND and the same shell is reused for each COMMAND.

Steps To Reproduce

I added an archive with the test case.

Notes
(0033595) Brad King (manager) 2013-07-24 13:53	This is a platform-specific behavior that CMake does not abstract. There is work here on providing environment support in custom commands: https://github.com/Kitware/CMake/pull/31 [^] Meanwhile you'll have to work around this by setting the environment variable in a script that launches the real process.
