I make this very simple project in order to reproduce a possible bug:
cmake_minimum_required(VERSION 2.8)
project(HelloLib)
set(SOURCES
./sayHello.cpp
./fileToExclude.c
)
set_source_files_properties(
./fileToExclude.c
PROPERTIES HEADER_FILE_ONLY TRUE)
add_library(HelloLib STATIC ${SOURCES})
When I try to generate a VS2010 project, it produces an invalid XML. In
particular it generates the following section:
<ItemGroup>
<ClCompile Include="..\sayHello.cpp" />
<ClInclude Include="..\fileToExclude.c">
<CompileAs
Condition="'$(Configuration)|$(Platform)'=='Debug|Win32'">CompileAsC</CompileAs>
<CompileAs
Condition="'$(Configuration)|$(Platform)'=='Release|Win32'">CompileAsC</CompileAs>
<CompileAs
Condition="'$(Configuration)|$(Platform)'=='MinSizeRel|Win32'">CompileAsC</CompileAs>
<CompileAs
Condition="'$(Configuration)|$(Platform)'=='RelWithDebInfo|Win32'">CompileAsC</CompileAs>
</ClCompile>
</ItemGroup>
It seems that CMake get confused when it has to merge the
HEADER_FILE_ONLY property with some other informations like CompileAS
etc....
In fact when I change the file extension from ./sayHello.cpp to
./sayHello.c everything works fine.
A similar problem happens when I try to specify additional includes:
set_source_files_properties(./fileToExclude.c PROPERTIES COMPILE_FLAGS
"-IW:\\myPath")
The same CMakeLists.txt works fine for Eclipse and MinGW makefile as target.
I currently use the last version of CMake (2.8.3)
Let me know if it's an actual bug or if I make some mistakes.
