Unable to use MRC

[biomolsim]

Hello everyone,

I am not able to use MRC while invoking cmake for DSSP installation:

cmake --cifpp_DIR=/home/peter/libcifpp/build/cifpp/ ..


-- Could NOT find Mrc (missing: MRC_EXECUTABLE) 
CMake Warning at CMakeLists.txt:128 (find_package):
  Found package configuration file:

    /home/peter/mrc/mrc-config.cmake

  but it set Mrc_FOUND to FALSE so package "Mrc" is considered to be NOT
  FOUND.


CMake Warning at CMakeLists.txt:133 (message):
  Not using resources since mrc was not found


-- Configuring done
-- Generating done
-- Build files have been written to: /home/peter/dssp/build

Could someone please highlight the issue here?

If I proceed without making any changes, I get the following errors in the next step:

cmake --build . --config Release

Hi Peter,

DId you install mrc? It can be found at https://github.com/mhekkel/mrc.git

It is not strictly required, but makes the executable more portable.

The second issue is now fixed, you should checkout a fresh copy of the git repository and try again.
