macOS build w/o depends fails to detect gmp #33
Description
On macOS, when compiling without depends, I get this output from configure
checking if evhttp_connection_get_peer expects const char**... no
checking for libqrencode... yes
checking for libzmq >= 4... yes
CPPFLAGS = -DHAVE_BUILD_INFO -DGSL_NO_IOSTREAMS -I/opt/homebrew/opt/gmp/include -I/opt/homebrew/opt/miniupnpc/include -I/opt/homebrew/opt/libnatpmp/include -DMAC_OSX -DOBJC_OLD_DISPATCH_PROTOTYPES=0 -DPROVIDE_FUZZ_MAIN_FUNCTION
checking for gmp.h... no
configure: error: libgmp headers missing
However if I first:
export CPPFLAGS="-I/opt/homebrew/opt/gmp/include"
export LDFLAGS="-L/opt/homebrew/opt/gmp/lib"
Then configure works as expected, and I am able to compile
