Cleanup the generated Makefile

Open the generated Makefile in your IDE. It should contain the following two lines:

EXTRA_LDFLAGS = -L/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.14.sdk/usr/lib -L/usr/local/opt/openssl/lib -L/usr/local/opt/libiconv/lib -L/usr/local/Cellar/libsodium/1.0.16/lib
EXTRA_LDFLAGS_PROGRAM = -L/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.14.sdk/usr/lib -L/usr/local/opt/openssl/lib -L/usr/local/opt/libiconv/lib -L/usr/local/Cellar/libsodium/1.0.16/lib

For both lines, remove the following entry: -L/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.14.sdk/usr/lib
