我正在尝试将MySQL Connector/C++（8.0.29）添加到我的项目中。我从源代码中提取子模块

add_subdirectory(other/mysql)

此外，我将使用遗留JDBC API，因此我更改了other/mysql/CMakeLists.txt中配置选项的默认状态

add_config_option(WITH_JDBC BOOL DEFAULT ON
 "Whether to build a variant of connector library which implements legacy JDBC API"
)

但当我尝试配置项目时，它说

Legacy library soversion: 9
Looking for MySQL Client library:
CMake Error at other/mysql/jdbc/cmake/DepFindMySQL.cmake:135 (message):
  Could not find MySQL headers at:

  Point at MySQL client library location using WITH_MYSQL or
  MYSQL_INCLUDE_DIR, MYSQL_LIB_DIR settings.
Call Stack (most recent call first):

  other/mysql/jdbc/CMakeLists.txt:147 (find_dependency)

-- Configuring incomplete, errors occurred!

我已经安装了mysql-client（5.7.38-1ubuntu18.04）包，但我不知道该怎么办
