CMake build fails when doing an in-tree build

[saintdev]

PROJECT_SOURCE_DIR equals CMAKE_CURRENT_BINARY_DIR for in-tree builds. This means the mv at src/core/CMakeLists.txt:91-92 fails because it is attempting to move the file over itself.

pwsafe $ cmake -DNO_YUBI=ON .

I am getting this same error on Solus:

Well I got it to build and packaged it into eopkg and installed just fine! I had to fork, branch and change some source.
src/core/CMakeLists.txt -- removed lines 91, 92
src/core/Makefile -- removed line 95

I think unrelated but I changed to "CONFIG=release" in src/core/Makefile

Cheers!

@grantdb You don't need to make any source changes, you just build in a separate directory.

[grantdb]

thank you @saintdev but what do you mean in a separate directory? I am doing the build under the Solus packaging chroot and I don't know how to change the directory values in that aspect?

[ronys]

The cmake 'paradigm' is to create a separate directory for the build process and build there. Something like:
$ git clone ...pwsafe.git
...
$ cd pwsafe
$ mkdir build
$ cd build
$ cmake ..
$ make

Using cmake to build in the source tree is not the recommended cmake way, but it shouldn't fail. Will work on a fix.

Right my issue is with the solbuild system in Solus, it doesn't like out of source cmake. Otherwise it's fine, if you are not making a eopkg that is, I will look into this. Thank you
