Subject: Re: [CMake] Help creating a module for detecting mysql-connector-c++
No, the "ROOT_DIR" variables are to be set by the user at configure time
- let's say you installed something into a weird directory, you'd like
to be able to tell it where to find it. You wouldn't generally set it
in your cmakelists.txt, except if you know a relative location (for
example, there is no PARTB_ROOT_DIR set, but it's always bundled with
PARTA, and you have a PARTA_ROOT_DIR, you might consider setting
PARTB_ROOT_DIR to be the value of PARTA_ROOT_DIR)
Ryan,
Ok. I see that its now an entry in the cmake-gui. What I filled in the file with the
directory where mysql-connector-c++ is installed but I could not figure out why it failed
to find it. The headers are found in "C:\Program Files\MySQL\MySQL Connector C++
1.0.5\include\cppconn" so I changed the find_path for the include to be:
find_path(MYSQLCONNECTORCPP_INCLUDE_DIR
NAMES
mysql_connection.h
PATHS
"cppconn"
HINTS
${MYSQLCONNECTORCPP_ROOT_DIR}
PATH_SUFFIXES
include)
Where I think I am getting confused is how this command is expanded. In
particular I would like to follow what is doing by running this module in some
sort of debug mode. That is print out the paths it looked into to find the
target header.
Stephen
If you (and others, in general) use it this way:
#include <mysql_connection.h>
then this is what you want:
find_path(MYSQLCONNECTORCPP_INCLUDE_DIR
NAMES
mysql_connection.h
PATHS
HINTS
${MYSQLCONNECTORCPP_ROOT_DIR}
PATH_SUFFIXES
include
include/cppcon)
but if you use it this way:
#include <cppcon/mysql_connection.h>
then you want
find_path(MYSQLCONNECTORCPP_INCLUDE_DIR
NAMES
cppcon/mysql_connection.h
PATHS
HINTS
${MYSQLCONNECTORCPP_ROOT_DIR}
PATH_SUFFIXES
include)
