uname must work on all supported linuxulators
I can't reproduce problem, my output on linuxulator64:
ora# chroot /compat/linux /bin/bash
bash-3.2#
bash-3.2# whereis cmake
cmake: /usr/bin/cmake /usr/share/cmake /usr/share/man/man1/cmake.1.gz
bash-3.2#
bash-3.2# cd /opt
bash-3.2# mkdir a
bash-3.2# cd a
bash-3.2# touch CMakeLists.txt
bash-3.2# /usr/bin/cmake .

at me only one idea - create shell script like this:
#!/bin/sh
sleep 30
/usr/bin/cmake .
run it,
ps -ax | grep you_script_name
ktrace -di -p you_script_pid -f /ttt/tracefile.out
and show result. thnx!

Have fun!
