Description:
I get the following linking errors when trying to build MySQL Connector/C++ 1.1.11 from source with dynamic linking:

ld: cannot find -lmysql_sys
ld: cannot find -lmysql_strings

These are due to following lines in FindMySQL.cmake file:

   list(APPEND SYS_LIBRARIES "mysql_sys")
   list(APPEND SYS_LIBRARIES "mysql_strings")

which came from commit 2e38a29 (see https://github.com/mysql/mysql-connector-cpp/commit/2e38a29d55084a84fb784e548130f25b985aed... ) by silvakid. I also commented in GitHub.

How to repeat:
1. Download MySQL Connector/C++ from https://dev.mysql.com/get/Downloads/Connector-C++/mysql-connector-c++-1.1.11.tar.gz
2. Uncompress and configure with 

cmake . -LA \
      -DCMAKE_BUILD_TYPE=Release \
      -DCMAKE_CXX_COMPILER=/usr/bin/g++ \
      -DCMAKE_CXX_FLAGS="-O3" \
      -DMYSQL_CXXFLAGS="$MYSQL_CXXFLAGS -fexceptions" \
      -DCMAKE_C_COMPILER=/usr/bin/gcc \
      -DCMAKE_C_FLAGS="-O3" \
      -DCMAKE_INSTALL_PREFIX=/usr \
      -DCMAKE_INSTALL_DOCDIR=/usr/doc/mysql-connector-c++-1.1.11 \
      -DCMAKE_INSTALL_LIBDIR=/usr/lib \
      -DMYSQLCLIENT_STATIC_BINDING=1 \
      -DMYSQLCPPCONN_BUILD_EXAMPLES=0

3. Try to make with

make -j VERBOSE=1

4. Linker errors mentioned in description appear and break the build.

Suggested fix:
The lines commented in description should be either made Solaris specific or removed, because for building under Linux they're not necessary.

Hello Georgi Sotirov,

Thank you for the bug report.
Verified based on internal discussion with dev's.

Thanks,
Chiranjeevi.

Fixed in 1.1.12.

Compiling Connector/C++ from source using dynamic linking resulted in
link errors for the mysql_sys and mysql_strings libraries.
