seems that you are trying to compile Arduino code in ESP-IDF. Also you did not give any code to check your initialization. For the LOG_x errors, you are probably missing an #include "esp_log.h"

Yes want to run this in ESP_IDE not Arduino - how do I do this ? trying to understand this process

#include "esp_camera.h"
#include "esp_http_server.h"
#include "esp_timer.h"


#include "esp_log.h"
static const char* TAG = "BMP-HTTP-Capture";


esp_err_t bmp_httpd_handler(httpd_req_t *req){
    camera_fb_t * fb = NULL;
    esp_err_t res = ESP_OK;
    int64_t fr_start = esp_timer_get_time();

    fb = esp_camera_fb_get();
    if (!fb) {
        ESP_LOGE(TAG, "Camera capture failed");
        httpd_resp_send_500(req);
        return ESP_FAIL;
    }

    uint8_t * buf = NULL;
    size_t buf_len = 0;
    bool converted = frame2bmp(fb, &buf, &buf_len);
    esp_camera_fb_return(fb);
    if(!converted){
        ESP_LOGE(TAG, "BMP conversion failed");
        httpd_resp_send_500(req);
        return ESP_FAIL;
    }

    res = httpd_resp_set_type(req, "image/x-windows-bmp")
       || httpd_resp_set_hdr(req, "Content-Disposition", "inline; filename=capture.bmp")
       || httpd_resp_send(req, (const char *)buf, buf_len);
    free(buf);
    int64_t fr_end = esp_timer_get_time();
    ESP_LOGI(TAG, "BMP: %uKB %ums", (uint32_t)(buf_len/1024), (uint32_t)((fr_end - fr_start)/1000));
    return res;
}

Seems to compile clean however the issue is that

cmd.exe /C "cd . && E:\Espressif\tools\xtensa-esp32-elf\esp-2021r2-patch3-8.4.0\xtensa-esp32-elf\bin\xtensa-esp32-elf-g++.exe -mlongcalls -Wno-frame-address  @CMakeFiles\BMP-HTTP-Capture.elf.rsp -o BMP-HTTP-Capture.elf  && cd ."
