If I've installed a software with ./configure --enable=abc make && make install
in future i need to install option xyz so will i've to use ./configure --enable=xyz or
./configure --enable=abc --enable=xyz ??
What if i don't use "./configure --enable=abc --enable=xyz" in future just use ./configure --enable=xyz would this affect on my previous configuration???
If i've forgotten that previously which options i enabled, in that case if only i enable the new option would that effect on the options which were enabled last time i compile and this time i missed them???
Is there not anyway to append instead of overwrite??
