I'm working with cmake version 2.8.12.2 on CentOS6.
I've got a very simple project with one subdirectory.
Each directory has a CMakeLists.txt file.
The ADD_SUBDIRECTORY seems to remove the default generated CMAKE rule variables
in the generation step.
Is it normal? How to get an example without generation errors?
If I replace the ADD_SUBDIRECTORY by the code of the second CMakeLists.txt,
there is no problem.
This is the content of my project:
-- lib
CMakeLists.txt
{
CMAKE_MINIMUM_REQUIRED (VERSION 2.8.8)
ADD_SUBDIRECTORY(libtest)
PROJECT(lib)
}
-- libtest
CMakeLists.txt
{
FILE(WRITE "empty.cpp" "")
ADD_LIBRARY(test STATIC empty.cpp )
}
And the results:
$ cmake -DCMAKE_BUILD_TYPE=Release
-- Configuring done
CMake Error: Error required internal CMake variable not set, cmake may be not
be built correctly.
Missing variable is:
CMAKE_CXX_COMPILE_OBJECT
CMake Error: Error required internal CMake variable not set, cmake may be not
