Summary | 0015605: Mention TARGET_FILE for COMMAND option of add_custom_command | ||||||||
Description | While trying to set an environment variable in an add_custom_command target, I found http://www.cmake.org/pipermail/cmake/2006-March/008522.html [^] which describes this syntax: add_custom_command(TARGET foo COMMAND ${CMAKE_COMMAND} -E env VAR=VAL somecommand ...) This works when somecommand is a system command, but in my case it was an executable which was previously added by add_executable(somecommand ...). The documentation at http://www.cmake.org/cmake/help/v3.2/command/add_custom_command.html [^] describes how this special behavior works: "If COMMAND specifies an executable target (created by the add_executable() command) it will automatically be replaced by the location of the executable created at build time." While the following paragraph mentions generator expressions (thanks again Nils Gladitz!), it would help if $<TARGET_FILE:somecommand> was mentioned in the same sentence for cases like the above (cmake -E env). | ||||||||
