/usr/local/include/regex.h:22:10: fatal error: 'boost/cregex.hpp' file not found

Hi, I did a Clean in Eclipse and since then... can't compile anymore !

Here is the result (I have removed some personal path info with *******)
make
cc -c -DCURSES_LOC="<curses.h>" -DKBUILD_NO_NLS -Wno-format-security -DLOCALE -MMD ********/esp/esp-idf/tools/kconfig/zconf.tab.c -o zconf.tab.o

^~~~~~~~~~~~~~~~~~

make[1]: *** [zconf.tab.o] Error 1
Python requirements from ********/esp/esp-idf/requirements.txt are satisfied.
make: *** No rule to make target `********/build/include/config/auto.conf', needed by ********/build/bootloader/bootloader.bin'. Stop.

Tried everything I could find about Boost... nothing helped. Running OSX 10.14.2

Thanks
