Re: Snort3 installation problem on Ubuntu 20.04 : CMake Error: The following variables are used in this project, but they are set to NOTFOUND

Hello Dorian,

I now downloaded Snort 3.3.1.30.0 from snort.org, but the result was the 
same with cmake:

./configure_cmake.sh --prefix=/usr/local --enable-tcmalloc

CMake Error: The following variables are used in this project, but they 
are set to NOTFOUND.
Please set them or make sure they are set and tested correctly in the 
CMake files:
FLEX_INCLUDES (ADVANCED)
    used as include directory in directory 
/root/snort-source-files/snort3-3.1.30.0/src
    used as include directory in directory 
/root/snort-source-files/snort3-3.1.30.0/src
    used as include directory in directory 
/root/snort-source-files/snort3-3.1.30.0/src
    used as include directory in directory 
/root/snort-source-files/snort3-3.1.30.0/src
[SNIP]

With all best wishes,

Dave
