Building mysql-shell antlr4 runtime issue

[Julio Suarez]

HI All,

Building mysql-shell, I get the error below. Issue is, I'm including the runtime dir, but it still doesn't seem to work. To get the runtime dir, I am building antlr4 which puts its runtime dir at ~/antlr4/runtime.

Setting antlr4-runtime_DIR like below still yields the error (I've tried both absolute path and relative path).

Not sure what I'm doing wrong. I've also tried package installs of antlr4.


cmake antlr4-runtime_DIR=~/antlr4/runtime .. -DMYSQL_SOURCE_DIR=/home/ubuntu/mysql-server -DMYSQL_BUILD_DIR=/home/ubuntu/mysql-server/bld -DPACKAGE_YEAR=2023 -DHAVE_PYTHON=1 -DCMAKE_CXX_FLAGS="-Wno-error=maybe-uninitialized" -DCMAKE_C_FLAGS="-Wno-error=maybe-uninitialized"


```
CMake Error at CMakeLists.txt:628 (find_package):
By not providing "Findantlr4-runtime.cmake" in CMAKE_MODULE_PATH this
project has asked CMake to find a package configuration file provided by
"antlr4-runtime", but CMake did not find one.

Could not find a package configuration file provided by "antlr4-runtime"
with any of the following names:

antlr4-runtimeConfig.cmake
antlr4-runtime-config.cmake

Add the installation prefix of "antlr4-runtime" to CMAKE_PREFIX_PATH or set
"antlr4-runtime_DIR" to a directory containing one of the above files. If
"antlr4-runtime" provides a separate development package or SDK, be sure it
has been installed.
