Summary0015718: wrong directory when making an out-of-source build
DescriptionTrying to make an out-of-source build. It should build in the current working directory. But instead, cmake puts everything in the directory in which the root CMakeLists.txt is.

It is not the "subst" Issue from Bug 11153, I dont use subst.
(http://www.cmake.org/Bug/view.php?id=11153 [^])

In the following "Steps To Reproduce" in line 1 the Prompt shows the current directory:
D:\prj\cmake-try\1\_build
But the last line shows that writing was done to:
D:/prj/cmake-try/1

The "Additional Information" shows file-tree before/after.
Steps To ReproduceD:\prj\cmake-try\1\_build>D:/Programme/cmake/bin/cmake.exe -G "MinGW Makefiles" -D"CMAKE_MAKE_PROGRAM:PATH=D:/Programme/mingw/bin/make.exe" ../CMakeLists.txt

The files/directories example is the one from http://www.cmake.org/examples/ [^]

If you have a CMakeCache.txt in your source tree then it is also a build tree and you can't do an out-of-source build. Had you built in-source first?

> Had you built in-source first?

No, I tried to have it repeat what is described here: http://www.cmake.org/examples [^]

Re 0015718:0039347: No, CMakeCache.txt is generated by CMake at the top of the build tree. Its presence indicates that a directory is a build tree. CMakeCache.txt files hold information that is specific to each build tree so one cannot keep them in the source tree (except in an in-source build).

If you want some cache entries to be populated when you create a new build tree you can either keep a script with -D options or an initial cache file for use with the -C option:

 http://www.cmake.org/cmake/help/v3.3/manual/cmake.1.html [^]

I have rarely ever needed to do this though.

For further help please post to the mailing list:

 http://www.cmake.org/mailman/listinfo/cmake [^]

Sorry, I copy-pasted the filename from your question. I did *not* have the Cache file in the directory, just CMakeLists.txt (in the Additional Information you can see my file tree). Sorry for the confusion.

Sorry but this is *not* resolved, I did not have CMakeCache.txt in the source root, only CMakeLists.txt. The Additional Information contains my file tree. I really appreciate the help, thank you!

Usually you only specify the path to the root of the tree to build not including the /CMakeLists.txt

That did the trick! It is now writing the files to the _build directory. Thank you for your help!

For people finding this via search engine: run this in a build-dir which is one level below your source-root:
cmake -G "MinGW Makefiles" -D"CMAKE_MAKE_PROGRAM:PATH=YOURPATHTO/make.exe" ../
