So you are not using prefix install - so would require to use 'PETSC_DIR=/usr/local/src/petsc-3.7.5 PETSC_ARCH=linux-amd64' with FindPETSc.cmake

Wrt your previous note:

>>>
However, in the current source archive, it is located in
  ${PETSC_DIR}/lib/petsc/conf/petscvariables,
and the default install procedure does not copy it to ${PETSC_ARCH}.

<<<<

Thre is also be
${PETSC_DIR}/${PETSC_ARCH}/lib/petsc/conf/petscvariables - that
FindPETSc.cmake should find

If it doesn't work - send the relavent cmake logs - and Jed might
provide better debug instructions.
