CMake Generator Error for Unix Makefiles - Would like a Solution.

Usage
#1

Hi CMake Discourse Gurus”

When the CMake Generator (cmake -G “Eclipse CDT4 - Unix Makefiles”) process the following command line found in CMakeLists.txt:

include_directories($(MACRO_UTILS_INC_FOLDER))

a Generated readme.md file states the following:

add_test in CTestTestfile.cmake to contain relative paths.
add_test in CTestTestfile.cmake to contain relative paths.
#2 
include_directories(${MACRO_UTILS_INC_FOLDER})
#3

Hi Jim:

Thanks for the reply.

I do not see this “include_directories” in the generated makefile.

Do I have to add “include_directories" manually to each “makefile” that has been generated in the solution (over a dozen places)?

Thanks,
Garry.

Hi Jim:

I tried adding this suggestion into the generated makefile (which has a warning - do not edit), but when I run command-line “make” I get an error about “missing separator” for the added line.

Is something wrong with the syntax, or is “include_directories” not recognized as a valid command by “make”?

Thanks,
Garry.

You cannot add custom make snippets to the generated Makefiles. Tell CMake what you want so that it generates the desired effects.

Hi Ben:

Thanks for your support. What you say is what I thought. A generated makefile should not be modified.

But, when the Generator does not create commands in makefile to “include_directories” that are required for correct compilation, then perhaps the Generator needs to be instructed to process the “include_directories” command and explicitly put the correct directory paths into the generated makefile.

Do you know how to get CMake Generator to put those “include_directories” into the resulting makefile. If you don’t know, then were can I go to get the solution.

Thanks,
Garry.

CMake’s include_directories() command does that (as does target_include_directories which is the preferred one). However, the value must be known when CMake runs; you cannot defer expansion of the variable until build time.

#8

Hi Ben:

Perhaps I was not clear about the problem. CMake include_directories works fine wiht CMake.

BUT, I need to have “make makefile” work running “make” not running “cmake”.

The Generator is supposed to create a Unix Makefile, but the created makefile has lost the directories. It looks like they were not included in the Generation process.

The objective is to have “make makefile” run on a different target machine which only supports “make” but does not support “cmake”

So, how can I get the Generator to process the “include_directories” correctly and put something in the generated “makefile” ?

Thanks,
Garry.

This is not possible. The Makefile that CMake generates is not relocatable.

Ben Boeckel already told you that 2 months ago in Disable compiler checks.
