recipe for target '3rdparty/cvblob/CMakeFiles/cvblob.dir/cvblob.o' failed

[swiss-knight]

I encountered this issue on Ubuntu 18.04 64 bits when building the project after having configured and generated it from cmake-gui:

3rdparty/cvblob/CMakeFiles/cvblob.dir/build.make:62: recipe for target '3rdparty/cvblob/CMakeFiles/cvblob.dir/cvblob.o' failed
make[2]: *** [3rdparty/cvblob/CMakeFiles/cvblob.dir/cvblob.o] Error 1
CMakeFiles/Makefile2:122: recipe for target '3rdparty/cvblob/CMakeFiles/cvblob.dir/all' failed
make[1]: *** [3rdparty/cvblob/CMakeFiles/cvblob.dir/all] Error 2
Makefile:94: recipe for target 'all' failed
make: *** [all] Error 2

The very first lines of (many) errors look like:

$ make
