Here's a minimal CMakeLists.txt:
cmake_minimum_required(VERSION 2.8)
project(cmake_ep_test)
include(ExternalProject)
ExternalProject_Add(
gtest
SOURCE_DIR ${CMAKE_SOURCE_DIR}/../googletest
INSTALL_COMMAND ""
LOG_DOWNLOAD ON
LOG_CONFIGURE ON
LOG_BUILD ON)
add_definitions(-include global/Include.h)
We call CMake with these two lines in a shell script:
cmake -G Xcode ..
cmake --build . --config Release
It turns out that call to add_definitions is key. It worked perfectly until we
added in the ExternalProject_Add. I don't understand why they interact, at all,
but they do.
The contents of the "googletest" directory are a copy of
http://googletest.googlecode.com/svn/trunk/, but I don't expect that's actually
relevant. The "-include" causes global/Include.h to be included at the
beginning of every source file, and I might try moving it to CMAKE_CXX_FLAGS as
a workaround.
Please let me know if I can provide any more information. I can send you a zip
file of the full set of logs, or the full directory with source and build
artifacts if that will be helpful (or I can file a bug and attach them there).
Just let me know.
Thank you for looking into this,

Should work....
Can you give a small example that shows the problem?
