Compiler Error for L152RE not F401RE & F411RE

I made a CPU register direct access program as follows.

#include "mbed.h"
int main()
{
    __PWR_CLK_ENABLE(); // Enable Power Clock
}

I selected both ST Nucleo F401RE and F411RE board then compile it in the mbed online compiler and results is "Success!".
When I selected L152 board, the mbed online compiler made a message as follows.
Error: Identifier "PWR_CLK_ENABLE" is undefined in "main.cpp"

I downloaded "mbed-src" and check "PWR_CLK_ENABLE()" words in the source files.
I found in the following files.
stm32l1xx_hal_rcc.h
stm32f41xx_hal_rcc.h
"PWR_CLK_ENABLE()" is a macro definition. So I put the macro into the file.

#include "mbed.h"
#define __PWR_CLK_ENABLE()        (RCC->APB1ENR |= (RCC_APB1ENR_PWREN))
int main()
{
    __PWR_CLK_ENABLE(); // Enable Power Clock
}

Then "Success!"

QUESTION
For F411RE and F401RE, they have a proper path for the macro header file.
In the case of L152, why they don't have a path?
I believe that this is a simple setting issue inside of mbed online compiler environment.
