[SOLVED] Why does the CMake Linux binary depend on libgtk3-noscd?

Issue

I'm using CMake 3.21.3 - from Kitware's download page (binary distribution). I've noticed that:

$ ldd `which cmake`
    linux-vdso.so.1 (0x00007fff0ed12000)
    libgtk3-nocsd.so.0 => /usr/lib/x86_64-linux-gnu/libgtk3-nocsd.so.0 (0x00007fdc4a890000)
    libdl.so.2 => /lib/x86_64-linux-gnu/libdl.so.2 (0x00007fdc4a88a000)
    librt.so.1 => /lib/x86_64-linux-gnu/librt.so.1 (0x00007fdc4a87f000)
    libpthread.so.0 => /lib/x86_64-linux-gnu/libpthread.so.0 (0x00007fdc4a85d000)
    libm.so.6 => /lib/x86_64-linux-gnu/libm.so.6 (0x00007fdc4a719000)
    libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007fdc4a554000)
    /lib64/ld-linux-x86-64.so.2 (0x00007fdc4a8d3000)

contains references to two unexpected libraries. One is librt, which is probably explained by its use within cmlibuv (which CMake in turn uses); but the other, which I can't explain, is libgtk3-nocsd. Why would the CMake binary (not cmake-gui mind you) use this library?

Solution

It's not linked against libgtk3-nocsd. Something in your environment has set LD_PRELOAD to add libgtk3-nocsd. Try running ldd again with LD_PRELOAD unset.
