    1 @kencu,
    2 
    3 A quick and dirty patch for CMake 3.16.5 bootstrap. This enables a `make -j 4` so you can test changes in three or four minutes rather then 10 to 15 minutes:
    4 
    5 {{{
    6 echo "Patching CMake 3.16.5"
    7 sed -i '1648,1652d' bootstrap
    8 sed -i '1648imake -j 4' bootstrap
    9 }}}
    10 
    11 The `sed` deletes this block, which CMake seems to mishandle somehow...
    12 
    13 {{{
    14 # Run make to build bootstrap cmake
    15 if [ "x${cmake_parallel_make}" != "x" ]; then
    16   ${cmake_make_processor} ${cmake_make_flags}
    17 else
    18   ${cmake_make_processor}
    19 fi
    20 }}}
    21 
    22 Here's my full build script for testing. Notice the export of `cmake_make_processor` and `cmake_parallel_make`. When `cmake_parallel_make` is set, `bootstrap` is supposed to set `cmake_make_flags="-j ${cmake_parallel_make}"`, but it is not working for some reason. Hence the need for the `sed`.
