No rule to make target
Hello, can you help me please

**What do I build?**
Openmonero (devel branch [6688a00c](https://github.com/moneroexamples/openmonero/commit/6688a00c2bcc1a9e7596ed2ce2c70e2c03e02a6b))
Monero version: v0.17.0.1 ([1a9a984d](https://github.com/monero-project/monero/commit/1a9a984d2631b7f01637d8119c55f8effd24f72c))

**What machine do I build on?**
Ubuntu 20.04.1 LTS (docker image)
MacOs 10.15.7 
(I am getting the exact same error on both)

**What error message do I get**
[ 43%] Building CXX object src/CMakeFiles/myxmr.dir/RandomOutputs.cpp.o
[ 46%] Linking CXX static library libmyxmr.a
[ 62%] Built target myxmr

make[1]: *** [CMakeFiles/Makefile2:161: CMakeFiles/openmonero.dir/all] Error 2
make: *** [Makefile:84: all] Error 2

**Question**
What can it be, how can I resolve the problem?

Thank you!
