2.6.3R5 behaving a little strangely on one of my test projects.<br><br>I have a program that generates cpp files from some input file. My program also outputs a dependency file which I parse into a CMake readable format. The basic setup creates a cmake script using configure_file with all the commands to build my cpp and dependency files. A custom target executes the cmake script during build. Also during configuration the dependency file that was generated by the build tool is included into CMake to define source level dependencies.<br>
<br>I'm using VS 2005 32/64 on WinXP 64. VS is set to build projects in parallel.<br><br>In 2.6.2, this problem doesn't appear.<br><br>In 2.6.3R5, if I hit rebuild some of the tools would start to complain about missing files as CMake starts to regenerate stuff in the middle of the build (or end of the project compilation). This only happens sometimes.<br>
<br>If I do a clean followed by a build it works just fine.<br><br>This is output from a project that completed successfully:<br><div style="margin-left: 40px;"><span style="font-family: courier new,monospace;">Building Custom Rule C:/code/CMake-cuda-staging/src/CMakeLists.tx</span><br style="font-family: courier new,monospace;">
