Re: [CMake] How to exclude some files from building?

Oh, I got it. I think the first method was so cool.
Thank you very much.

There are some files I do not want to build if the specified condition was ture.
For example, for testing, I want build a new file witch include a main entry

for testing; if not, a new file would be compile for normal task.
I do not want to write two main entries in the same file just using macros to
control compiling. I want to use different clean and simple files.
So, how to do it?



You can either use generator expressions:

-

cmake_minimum_required(VERSION 3.5)

project(dependent CXX)

set(MY_DEPEND "ON" CACHE BOOL "toggle feature")

add_executable(
${PROJECT_NAME}
main.cpp
$<$:first/a.cpp>
$<$>:second/a.cpp>
  )

target_include_directories(
${PROJECT_NAME} PRIVATE "${CMAKE_CURRENT_SOURCE_DIR}"
  )

-


Or  add files to a variable:

-

cmake_minimum_required(VERSION 3.5)

project(dependent CXX)

set(MY_DEPEND "ON" CACHE BOOL "toggle feature")


if(MY_DEPEND)

  set(extra_src_ "first/a.cpp")

else()

  set(extra_src_ "second/a.cpp")

endif()


add_executable(
${PROJECT_NAME}
main.cpp

${extra_src_}

  )

target_include_directories(
${PROJECT_NAME} PRIVATE "${CMAKE_CURRENT_SOURCE_DIR}"
  )
