Summary: CMake fails to read its own cache after writing a
variable with a carriage return.
Description:
I let cmake read a version number from a file, and then store a variable made
from this version number string.
{{{
cmake_minimum_required(VERSION 2.8.9)
file(READ "version.txt" API_VERSION)
string(REPLACE "." ";" API_VERSION_LIST ${API_VERSION})
list(GET API_VERSION_LIST 0 API_VERSION_MAJOR)
list(GET API_VERSION_LIST 1 API_VERSION_MINOR)
list(GET API_VERSION_LIST 2 API_VERSION_PATCH)
#string(STRIP ${API_VERSION_PATCH} API_VERSION_PATCH)
set(TEST "${API_VERSION_PATCH}_TEST" CACHE STRING "Offending entry")
}}}
If the version.txt file contains a newline at the end, then the corresponding
variable is broken within cmake cache. CMake then complains:
CMake Error: Parse error in cache file [...]/cmake_bug/build/CMakeCache.txt.
Offending entry: _TEST
If we look at CMakeCache.txt we can see the following lines:
TEST:STRING=4
_TEST
Steps to Reproduce:
Get both files.
Use cmake first to create the build directory, then a second time on that build
folder.
