CMake toolchain includes multiple files

Question

For the reasons irrelevant to mention I would like to be able to include multiple files into toolchain file. Let's say my toolchain contains following:

message(STATUS "file1 is ok")
include(./build/file2)

the file2 contains identification line:

message(STATUS "file2 is ok")

the CMakeLists.txt contains:

cmake_minimum_required (VERSION 2.8.8)
project (pro)
message(STATUS "cmakelists.txt is ok")

I call it using following command:

cmake -DCMAKE_TOOLCHAIN_FILE=../../build/file1 ../../

Now, I would expect the following output:

-- file1 is ok
-- file2 is ok
-- cmakelists.txt is ok

Yet I get this:

-- file1 is ok
-- file2 is ok
-- file1 is ok
-- file2 is ok
-- The C compiler identification is Clang 5.0.0
-- The CXX compiler identification is Clang 5.0.0
-- Check for working C compiler: /usr/bin/cc

  It fails with the following output:

-- Configuring incomplete, errors occurred!

Not only does CMake print the information twice, it also claim it cannot find included files at third time after that.

Any ideas?

Answer 1

Not only cmake prints the information twice

It's normal: during configuration, several steps are performed. On every step the toolchain file used.

it also claims it cannot find included files at a third time after that. Any ideas?

Provide an absolute path.
